I like “common first name, unusual middle name” combos. I currently have four on my UC:
[name_f]Caroline[/name_f] [name_f]Dove[/name_f]
[name_f]Alice[/name_f] [name_f]Verona[/name_f]
[name_f]Emma[/name_f] [name_f]Beatrix[/name_f]
[name_m]Jack[/name_m] [name_m]Leandro[/name_m]
and with even more out there middles, I like:
[name_f]Charlotte[/name_f] [name_f]Wildrose[/name_f]
[name_f]Sophie[/name_f] [name_f]Lunaria[/name_f]
[name_m]Mateo[/name_m] [name_m]Lysander[/name_m]
[name_f]Clara[/name_f] [name_f]Amethyst[/name_f]
